To Start: A Thought to Remember

“The Internet has no core, just an ever-expanding edge…”

– Wireless LANs are just the latest in a long line of edge technologies enhancing the user experience

Legacy Wi-Fi Wireless 2.0 Implications of Wireless 2.0 A distributed approach – the logical

answer

Legacy Wi-Fi

Convenience Wi-Fi– Meeting room and guest access

Security? What security?– WEP, TKIP, Strong Authentication?

Tactical Deployment– “Get it off my network!”– “If you are having problems, plug in”– Controllers were designed to tame this beast

Networking’s Redheaded Step Child!

Exhibit A for Wireless 2.0

MacBook Air – launched January 2008

Wireless: fast enough and reliable enough to be the only network!

No ports! No ports on thisside, either

Yesterday’s WLAN- Convenience Wi-Fi

- Guest Access

- Nomadic Users- Scanners & single

Even More Speed:Looking ahead to 802.11ac & 802.11ad

After “High” throughput (11n) comes “Very High” Two task groups formed

– 11ac: Gigabit at < 6 GHz (large backwards compatibility concerns with 802.11a/b/g/n)

– 11ad: Gigabit at 60 GHz (no backwards compatibility, but very short range)

Improvements on existing technologies– Coding: 256-QAM instead of 64-QAM– Channel width: Adds 80 & 160 MHz channels

Multiuser-MIMO (MU-MIMO)– Simultaneous beamforming to multiple receivers– Like Ethernet switching – reduces contention for medium

access

Strong driver of distributed forwarding

Implications of Wireless 2.0

Pervasive Deployment– Wi-Fi is becoming the primary access layer– Wi-Fi can save money, but to maximize the benefits, the Wi-Fi

implementation must itself be: • Cost-effective, Scalable, Ease to Manage

Multiservice Infrastructure– Wi-Fi is now expected to be capable of

supporting any application, device, or user type…yet…• Wi-Fi is a shared medium with instantaneous variations in SNR

Security / Authentication– Strong Authentication Integration, Segmentation, WIPS – Secure Flexible Guest Networking

Risk Mitigation– Availability, Performance, Redundancy

Lower Opex example- Visibility instead of just Statistics

Good connection

High data rates & high successful transmission rates

Marginal connection

Lower data rates / lower successful transmission rates

Poor connection

Low data rates / low successful transmission rates

Client Health

Calibrated to the organizations deployment goals

• High density, performance oriented network

• Normal density network

• Low density, coverage oriented network

At a glance understanding of a clients health

Easy to drill into problem client info

A distributed approach: the logical answer

Distributed Forwarding with Policy Enforcement

– Local best-path forwarding – Policy applied before forwarding

Distributed Intelligence– Microsecond-granular handling

• Airtime & Statistics

– Firewall, QoS, RADIUS, VPN

Distributed Processing– Real-time airtime mgmt– SLA compliance– Power to track every client in the

network and adjust parameters based on client health

A distributed approach: the logical answer

No Single Points of Failure– Dual-homing (Data/PoE)– Stateful failover & best-path

forwarding– Seamless secure roaming

Path Resiliency– Dynamic mesh failover – Track-IP

Branch Survivability– Distributed control & data

forwarding – Integrated RADIUS server

• Allows for local authentication or AAA caching

• Can link to a central directory
